camrelizumab combined with chemoradiotherapy in advanced esophageal cancer.

Conditions: Esophageal Neoplasms; Esophageal Diseases; Digestive System Neoplasms

Summary: this is a prospective single-arm exploratory clinical study. the efficacy and safety of camrelizumab combined with chemoradiotherapy and camrelizumab combined with chemotherapy were evaluated in patients with advanced esophageal cancer who had not previously received any systemic antitumor therapy for esophageal cancer.
